Just tested Mike's suggestion and "continue" does the trick.

Here's a test that verifies that..

 NSArray *myStuff = [[NSArray alloc]initWithObjects:@"A", @"B", @"Puppies", @"C",@"D", nil];

    for (NSString *myThing in myStuff) {
        if ([myThing isEqualToString:@"Puppies"]) {
            continue;
        }

        NSLog(@"%@",myThing);

    }
